I know that Apple is soon to require 64 bit apps on its OSX High Sierra.

When checking my System Report for software, I noticed that Nisus Thesaurus is 32 bit — it specifically identifies it as "No" re: its 64 bit status. I wonder how this will impact Nisus Writer Pro users. Are there plans to update the Thesaurus in the near future, or is it nothing to be concerned about?
